Patented Jan. 24, 1933 1 'UNITED STATES PATENT OFFICE mssn ammonia or BROOKLYN, NEW Yonx ing a cutaway space between them of a size f TRAVERSE BUTTON Application filed May 1,

. My invention relates to traverse buttons such, for instance, as are used on .quilling machines, which button is usually though not necessarilymade of porcelainfand is usually carried by a metal finger or arm.

This button is, in some respects, an improvement on my button which forms the subject matter of my application for patent Ser. No. 320,932, dated Nov. 21, 1928.

In using traverse buttons madeof both porcelain and metal, the buttons are usually held to the work by metal holders which are provided in their outer ends with jaws havand shape adapted to snugly receive the shanks of the buttons.

It is unavoidable that these jaws very frequently become sprung a trifle, and in such cases it is common to cement or shellac the buttons into their holders to make them hold securely in order to prevent the loosening andfalling out causedby vibration. This cementing or shellackingprocess consumes no little time; and one of the objects of the present invention is to provide means for removably locking the buttons on their respective holders without the use of shellac or cement. This feature of the present invention is not embraced in the previous application just above referred to. v

A very important feature of the present invention consists in the construction of its working face, which is not predominantly.

spherical, as is ordinarily the case with buttons of this character; but on the contrary is predominantly cylindrical in the direction of the travel of the button when at work. The

object of this feature is to insure the production ofa cone very evenly and tightly wound.

This gives adecided advantagein copping 1930. Serial xo.i44a, ooo.

mustthen be made as to how tightly and how evenly the copping should be done in order to insure that the given sized cone for;

which the machine is set shall yield the de- 1 sired weight. g If it fails to do so, as is often the case with the ordinary traverse button, the cops are bound to weigh less, besides be:

ing unevenly copped; and hence an unsalable in said projecting portion for securing the button in the holder.

The obj ectof the present invention is'therefore twofold, namely; to secure the traverse buttons on their respective holders without the use of shellac, cement, ,or the like; and

to insure the production of tightly and ly wound cops of uniform weight. w j,

The invention consists in certain novel features of construction and arrangement of evenparts, as will now be specifically described 7 and claimed, reference being had to the accompanying drawing, in which I Fig.7 1 is a top plan view of the usual metallic holder used for .holding traverse 7 buttons on quilling machines.

Fig. 2 is a view of the same with my improved traverse button secured thereon in operative position.

Fig. 3 is a similar viewrshowing slightly modified means for securing the button on the metallic holder. 1

- Fig. 4 is a side view of the device, as illustrated in Fig. 3, and, Fig. 5 is a side view of Fig. 2.

Fig. 6 is a top plan view of the form of button shown in Fig. 2; and, Fig. -7' is a similar view of the form of button shown in Fig. 3. r

Fig. 8 is a view of the wire spring holder used with the form of button shownin Figs. 2, 5, 6, and 9.

' line 13*13 of Fig. 7, with the securing pin I such as in common use in quilling machines,

omitted.

The numeral 1 designates the metal holder,

said holder being provided at its outer end with a bent-up section 2 for engagement with the frame of the machine; and at its forward end with opposing jaws 3 for engaging and holding the traverse: button. The ,numer 'al 4 designates the traverse button which has a shank 4a adapted to be snugly received into the semi-circular space 5 between the jaws 3 of theholder. This shank iwis provided on its opposing circular sides with parallel grooves .6 into which is received a spring "wire '7 for locking the button inits holder,as shown'in Figs. 2 and 5. Theportionb at the base'ofthe shank, between the buttonproperrand the grooves 65, is of a depthequal'tothe thickness of the metal holder 1.. f c v a c In them'odified form of buttonshown in Figs. 3, 4, 7, and 10, of the drawing, the

-' outer projecting end of the shank has a bore 8, into which is received a humped spring pin- 9' having a head 10 disposed ina plane at right. angles. to the plane of vthe hump in the pin. r 1

Attention is now called to a very important feature of the working face of my traverse button,.whichjfeaturev is more clearly illustrated in Figs."12 and 13 of the drawing,

from whichit willbe seen" that the face of the button is not spherical, but rather cylindrical, in its transverse direction. That is to say; it presents abroad, convex, cylindrical face 11 to the cop as it moves back and forth thereupon in feeding the thread thereto and laying itthereupon.

In operation, the shank of the button is inserted in the opening 5 between the jaws 3.

of the holder, in the usual way, with the top face of the button in engagement with the under side of the holder. This brings the parallel'grooves 6 just above the face of the jaws 3. The U-shaped spring wire 7 has its inwardlydnclinedfree ends sprung slightly I outward and entered in the groovesfi of the, shank of, the-button, as illustrated in Fig. 2 of the drawing. EThis bringsthe under side of the spring wire 7 into engagement with the upper fa'ceof thejaws 3, and locks the shank ofthe button against up-and-down movement in the holderl, so that no amount of vibration can ever 'cause'it to fall out, even though the jaws 3. may have. become somewhat sprung. Neither .will the springlock 7 ever work out from vibration, since its two opposite sides are naturally sprung inwardly slightly toward each other at their free ends, so that they automatically grip the shank of the button in the grooves 6. Hence it becomes apparent that no shellacking 'or cementing of the buttons in their holdersis ever necessary.-

in cases where the shank of the button is easily inserted into it. 1 j h In the modified form of button shank shown in Figs. 3,7, and 10, the bore- 8 and the humped spring pin 9 take the place of the grooves 6 and the U-shaped spring 7 of button in engagement with the under. side of the holder 1, as shown in Fig. 4 of the drawing. The head 10 of thispin, being disposed in a plane at right angles to the plane of the hump, keeps; the pin from'turning inthe bore 8, whilethe hump forms .a springpressing upwardly in' the bore 8,:and thus ,yieldingly presses] the" upper face of the button into constant engagement} with the under side of the jaws 3. f I

When the button is at work copping thread, the broad cylindrical face 11 presses evenly upon a considerable areaof the cop since 'it lies in parallel engagement therewith'for a material distance at each side of the point where the thread is being delivered to the cop, and as a result this arrangement insures a very tight, evenly wound,compact fine appearance, thus easily commandingthe 1 top of the market.

; H ving now described my invention,

the other form, to hold the top face of the I claim as new, and desire to protect, by Let tersPatent is a I V 1. In combination, a traverse button and a holder therefor, the button having a shank, and the holder having an opening for receiv ing the same, said shank projecting beyond the side of said holder'into which it is received, said projecting portionhaving an opening; and an upwardly-humped spring pin for extending through said opening to hold'the button on the holder, said pin'having a T-head extending in a direction atv right angles to the plane of said hump. 1

2. In a device of thecharacter described,- a traverse button having its working side in.

the form of a spherical surface cut away .cen

trally across the face thereof to produce a zone in the form of the segment of a cylinder extending in the direction in which the but-, ton is designed to travel on the cone, said side thereof into said zone merging at each spherical-surface. v

3. In a device of the character described,

a traverse button having its Working side in the form of a spherical surface cut away centrally across the face thereof to produce a zone in the form of the segment of a circle extending in the direction in which the button is designed to travel on the cone, said zone merging at each side thereof into said spherical surface, said spherical surface extending from said zone on either side thereof to the edge of the button.

In testimony whereof I affix my signature.
